USES/FORMS/SOURCES

USES

This copper compound has the greatest number of uses. It is used in agriculture, animal husbandry, steel-making, treatment of natural asphalts, and in the petroleum industry (Clayton & Clayton, 1994). It is used in leather manufacturing (Bhowmik et al, 2001). Copper sulfate has sometimes been used as an emetic (Clayton & Clayton, 1994), however, it is NOT RECOMMENDED FOR THIS PURPOSE.
Copper sulfate is used as an inorganic fungicide, algaecide, herbicide, and molluscide (TOXNET, 1986).
One of the constituents of Clinitest(R) tablets is copper sulfate, 20 mg per tablet (Prod Info Clinitest(R) tablets, 1996).
Copper sulfate may be found in childrens' chemistry sets and crystal gardens (Walsh et al, 1977; Gulliver, 1991). It is found in chemistry laboratories in colleges (Bhowmik et al, 2001).
Although uncommon in the US, copper sulfate has been a common agent used for suicide in India and Bangladesh (Bhowmik et al, 2001; Walsh et al, 1977).

FORMS

Copper sulfate is a naturally-occurring inorganic salt, and is available as dust, wettable powders, and fluid concentrates (TOXNET, 1986). It is blue or white rhombic crystals, crystalline granules, or hygroscopic powder (Lewis, 1996).

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

USES: Copper sulfate, a soluble copper salt, is used in agriculture, animal husbandry, steel-making, treatment of natural asphalts, in leather-making, and in the petroleum industry. It has also been used as an inorganic fungicide, algaecide, herbicide, and molluscide.

TOXICOLOGY: Copper sulfate produces hemolysis by increasing oxidation of hemoglobin sulfhydryl groups, leading to increased red blood cell permeability. Copper inhibits the sulfhydryl group enzymes, such as G6PD and glutathione reductase, which protect the cell from free oxygen radicals.

EPIDEMIOLOGY: In the US, copper sulfate toxicity is rare. In India and Bangladesh, copper sulfate has been a common agent used for suicide.

WITH POISONING/EXPOSURE

SUMMARY: Copper sulfate may be toxic by inhalation, ingestion, injection and topical exposure.
INGESTION: Acute ingestion can cause irritation, severe nausea and vomiting, salivation, abdominal pain, epigastric burning, hemolysis, gastrointestinal bleeding with hemorrhagic gastritis, hematemesis, and melena, anemia, hypotension, tachycardia, jaundice, seizures, coma, shock, and death. Hepatic and renal failure may develop several days after acute ingestion. Methemoglobinemia may rarely occur. Stools, vomitus, saliva, and mucous membranes are often stained green or blue.
INHALATION EXPOSURE: Burning copper sulfate may result in irritating and poisonous gases which may irritate the respiratory tract and lungs and can cause metal fume fever, a benign and self-limited condition manifesting with cough, chest tightness, chills, and muscle aches.
INJECTION: Intravenous and subcutaneous injection of copper sulfate can result in acute renal failure, gastrointestinal bleeding, coagulopathy, metabolic acidosis, hemolysis, hepatic injury, and death. Initial symptoms of vomiting, abdominal pain, hematemesis, and diarrhea can began within 15 minutes of the injections.
TOPICAL EXPOSURE: Copper sulfate is a strong irritant to skin and mucous membranes, including nose, throat, and eyes.

Copper sulfate is an eye irritant and can cause ulceration and turbidity of the cornea (HSDB). It is also a skin irritant and can cause an itching allergic eczema (HSDB). When ingested, it can cause metallic taste, a burning sensation in the stomach, vomiting, diarrhea, gastrointestinal tract bleeding, jaundice, liver or kidney damage, shock, coma, and methemoglobinemia and hemolysis (HSDB; (Todd, 1962; Todd & Thompson, 1965).

Copper sulfate poisoning has a fatality rate of 24.9% in southern Bangladesh. Gastrointestinal bleeding, hepatotoxicity, and kidney failure were the major clinical effects (Ahasan et al, 1994).

CHRONIC CLINICAL EFFECTS

In mice, inhaled copper sulfate caused an inflammatory response; it was felt to be the agent responsible for vineyard sprayer's lung (Eckert & Jerochin, 1982).

-FIRST AID

FIRST AID AND PREHOSPITAL TREATMENT

Copper sulfate is a caustic agent, capable of extensive mucosal damage, including perforation of the gastrointestinal tract. Prehospital decontamination with activated charcoal is not recommended because it may cause further complications and obscure endoscopy findings.

-RANGE OF TOXICITY

MINIMUM LETHAL EXPOSURE

SUMMARY

Acute poisonings from ingestion of copper sulfate, some of them fatal, were reported from New Delhi. Dosage estimates ranged from 1 to 12 grams of copper sulfate (Clayton & Clayton, 1994).

CASE REPORTS

Administration of 2 grams of cupric sulfate resulted in death in a 44-year-old woman (Stein et al, 1976).
In a series of 14 pediatric chemistry set poisonings, 7 cases including one fatality resulted from ingestion of copper sulfate solution. Mucklow (1997) estimated an incidence of 0.3 cases of chemistry set poisoning per 100,000 children (Mucklow, 1997).
A copper sulfate oral emesis solution (2.5 grams in 1750 milliliters of water) was given to a 25-year-old woman who had ingested about 20 tablets of diazepam (2.5 milligrams/tablet). She died 3 days later with death attributed to copper-induced acute hemolysis and acute renal failure (Liu et al, 2001).
A 22-year-old man developed severe abdominal pain, vomiting, diarrhea, metabolic acidosis, and intravascular hemolysis after intentionally intravenously injecting 1 gram of copper sulfate, mixed with water, into the right cubital fossa. He died approximately 3 days post-injection due to multi-organ failure (Behera et al, 2007).
A 19-year-old woman developed abdominal pain and vomiting that was blue in color after ingesting more than 10 g of copper sulfate solution. She was also hypersalivating and tachycardic. Endoscopy demonstrated grade 2 esophagitis, gastritis, duodenitis, and ulcerations, and a bronchoscopy indicated bronchial blue-green staining and tracheobronchitis. Her serum copper level was greater than 500 mcg/dL. On hospital day 1, she developed hemolysis, methemoglobinemia, and acute renal failure. Therapy included penicillamine 1.5 grams, hemodialysis, exchange transfusions, methylene blue, folate, and zinc. Chelation with calcium disodium edetate, dimercaprol, and trientine were unavailable. Following 2 courses of hemodialysis, copper was undetectable in the dialysate; however, her neurological status deteriorated and her renal function did not improve. The family withdrew care after 14 days, and the patient died (Eisnor et al, 2015).

MAXIMUM TOLERATED EXPOSURE

ACUTE

The lowest published toxic dose for humans by the oral route is 120 mcg/kg with nausea and vomiting reported (RTECS , 2002).
Doses as low as 250 mg of copper sulfate may result in toxic blood levels if spontaneous emesis does not occur or gastric evacuation is not undertaken (Stein et al, 1976). Even with forceful emesis, doses in excess of 1 gram copper sulfate may produce toxicity (Chugh et al, 1977).
DRINKING WATER: EPA limit for copper sulfate is 1 ppm in drinking water (TOXNET, 1986).

CASE REPORTS

PEDIATRIC

Ingestion of 3 grams copper sulfate resulted in hemolytic anemia and renal tubular damage in an 18-month-old boy (Walsh et al, 1977).
Ingestion of 30 mL of a super-saturated solution of copper sulfate (approximately 10 grams) resulted in serious toxicity (vomiting, anuria, lethargy, ECG abnormalities, intravascular hemolysis) with survival in a 2-year-old boy (Cole & Lirenman, 1978).

ADULT

Ingestion of 250 grams of copper sulfate was survived by a 42-year-old man (Jantsch et al, 1985).
A previously healthy 18-year-old man ingested approximately 8 grams of copper sulfate solution and reported to the hospital one hour later. He developed rhabdomyolysis, acute renal failure and hemolysis. Following aggressive chelation therapy, hemoperfusion and hemodiafiltration, the patient recovered (Takeda et al, 2000).
A 65-year-old man presented to the emergency department with nausea, blue-green vomiting, abdominal pain, and diarrhea, after ingesting approximately 25 mL of a liquid thought to be sparkling water but was later determined to be a diluted copper sulfate solution (100 g copper sulfate in 250 mL of water). Total estimated copper sulfate dose was approximately 10 g. Physical examination showed mucositis and pharyngitis, but there was no evidence of bleeding (no hematemesis and digital rectal exam was negative). An endoscopy indicated pharyngeal edema and diffuse gastroduodenitis without lesions. His plasma copper concentration at admission was 144 mcg/dL (N=70 to 170 mcg/dL). Following 4 days of chelation therapy, his plasma copper concentration decreased to 64 mcg/dL. There were no complications and the patient was discharged from the ICU the next day (Higny et al, 2014).

GLOVES

Specific recommendations and test data for this product type were not found in the available manufacturers' product literature.

GENERAL INFORMATION

This section provides a compilation of chemical resistance information and test data for specific protective clothing products. Chemical resistance information includes both degradation resistance ratings and permeation resistance data. This information is designed to assist in the selection of appropriate protective clothing. Only data on specific products and manufacturers are included. Generic information or recommendations are not provided since significant differences can exist in the chemical resistance for apparent similar product types.
Specific product information is organized by general product type (gloves, garments, and footwear), material type, and manufacturer. The category 'garments' may include totally encapsulating suits, splash suits, as well as other items (e.g., coveralls, jackets, and aprons). Specific manufacturers should be contacted to determine the features of available styles/models.
In addition to chemical resistance information, there are many critical variables in the selection of protective clothing which cannot be represented in this summary of the literature. Some factors to be considered in choosing protective clothing include, but are not limited to: overall clothing integrity, physical hazard resistance, durability, human factors, ease of decontamination, and cost. Overall clothing integrity refers to a specific design's ability to offer consistent protection for all clothing-covered areas of the body. Physical hazards include resisting the effects of abrasion, cuts, tears, and punctures. Human factors entail effects on wearer mobility, visibility, and hearing for garments; dexterity, tactility, and grip for gloves; ankle support and weight for footwear; and, any effect of the clothing on the function of the wearer. There are several variations in the design for gloves, garments, and footwear that affect these factors. Protective clothing must properly be sized and correctly fit the wearer to ensure its proper use and function.
As required in the U.S.A., protective clothing should be selected based on a risk assessment of the workplace. This risk assessment must account for the identification of existing as well as potential hazards and involve the recommendation of protective clothing appropriate for the identified hazards. Therefore, the recommendations in this section should not be used as the sole basis for decisions on choice of protective clothing, but rather should be used as a tool by qualified occupational health and safety professionals or other technically qualified persons in conjunction with a review of all mitigating factors. Consult the OSHA PPE Standard (29 CFR 1910.132 - 1910.138) for regulations and additional guidance regarding the selection and use of protective clothing and equipment. For general information on protective clothing selection, refer to the "PERSONAL PROTECTIVE EQUIPMENT - OSHA PUB 3077" document.
PROTECTIVE CLOTHING SELECTION

Determine the type of protective clothing item needed based on a risk assessment (e.g., gloves, garments, footwear).
For high risk situations, choose clothing that covers all parts of the body that may be exposed. In many cases, multiple clothing items will be required. Low risk situations may permit partial body protective clothing. Select protective clothing products that have reported chemical resistance data. High risk situations involving full body clothing or extended chemical contact often require permeation resistance data to determine the barrier effectiveness of materials used in the construction of clothing. Relatively low risk situations, where only splash or incidental exposure occur, may allow use of protective clothing based on degradation or penetration resistance data. Specifics on the interpretation of chemical resistance data are presented below.
Other factors must be considered in addition to chemical resistance. The selected chemical protective clothing item should offer the optimal combination of protection against identified hazards while allowing maximum function and comfort.

INTERPRETATION OF DEGRADATION RATINGS

Degradation refers to physical changes in a material as the result of chemical exposure. Degradation may become evident in visible changes, such as discoloration, swelling, delamination, deterioration, or disintegration. Degradation effects may also be measured by weight change or other changes in a material's physical properties (e.g., strength, elasticity, hardness).
Degradation resistance ratings are provided by manufacturers to rate the amount of degradation that occurs for a particular protective clothing material when contacted by a chemical. All degradation ratings are qualitative and include ratings, such as "EXCELLENT," "GOOD," "FAIR," "POOR," and "NOT RECOMMENDED." There is no standard test method for the measurement of chemical degradation resistance; therefore, manufacturer ratings may be based on different testing approaches. This makes comparison of degradation ratings between manufacturers unreliable.
The use of degradation resistance ratings alone to recommend protective clothing, particularly for high hazard situations, should be avoided. Degradation resistance testing does not directly assess the barrier quality of protective clothing, since materials can show relatively little degradation but still allow either permeation or penetration by a chemical. Degradation resistance ratings can be used to exclude protective clothing materials from consideration. Protective clothing materials with a "NOT RECOMMENDED" degradation resistance rating should never be used.
For some products, the rating "NO PENETRATION" is provided. This refers to penetration resistance test results that are based on a different procedure (American Society for Testing and Materials (ASTM) Standard Test Method F 903). Penetration resistance testing involves placing a material sample in a test cell, exposing the exterior side of the material to a chemical, and then observing the interior side of the material for visible signs of liquid penetration. Part of the test is conducted at an elevated pressure. Test results are reported as pass (no penetration) or fail (penetration detected). Unlike degradation testing, penetration testing provides an assessment of protective clothing material barrier performance. Since penetration resistance testing examines only observable amounts of liquid penetration, permeation may still occur. The use of penetration resistance data must be restricted to liquid chemicals, and should be limited to scenarios where there is no reasonable vapor exposure hazard under the conditions of exposure.

INTERPRETATION OF PERMEATION DATA

Permeation is the process of chemical movement through a material on a molecular level. Permeation resistance refers to the ability of a material to retard or prevent chemical movement through it. Permeation may occur without any visible signs of degradation.
Permeation resistance is measured using a test cell which is divided into two halves by a protective clothing specimen. Chemical is placed on the challenge side, while the collection side is periodically monitored for permeating chemical. Permeation data were obtained in accordance with the American Society for Testing and Materials (ASTM) Standard Test Method F 739 (Resistance of Materials Used in Protective Clothing to Permeation by Liquids and Gases), unless stated otherwise. In the case of chemicals that are classified as warfare agents, the data were obtained in accordance with the Military Standard 282 (MIL-STD-282) (Military Standard, Filter Units, Protective Clothing, Gas-Mask Components, and Related Products: Performance Test Methods).
Permeation rate is the amount of chemical that passes through a material for a measured surface area per unit time. In this section, permeation rate is expressed in micrograms per square centimeter per minute (mcg/cm(2)/min). The reported permeation rate is either the steady-state rate or the maximum rate observed during testing. In some cases, very large permeation rates exceed measurement techniques and are reported as ">" (greater than) or "HIGH."
Breakthrough time is the elapsed time, in minutes, from the time the chemical comes in contact with the material exterior surface, to the time that chemical is detected on the interior surface. When no breakthrough is detected, the breakthrough time is report as ">" the testing period. If permeation breakthrough is rapid, results are reported as "<" (less than) the earlier sampling time or as "IMMEDIATELY" (which usually means breakthrough in less than 4 minutes).
The breakthrough time should exceed the expected use period of the selected protective clothing. Additionally, there are several other factors that must be taken into account to provide appropriate protection.
Permeation testing is usually conducted with full strength, undiluted chemical for the duration of the test period. Actual exposures may involve diluted chemical for short or intermittent exposure periods.
Permeation testing is usually conducted at room temperature. Permeation occurs faster at elevated temperatures (short breakthrough times and higher permeation rates) and slower at reduced temperatures (long breakthrough times and lower permeation rates).
Permeation resistance of mixtures cannot usually be determined on the basis of the individual chemicals making up the mixture. Synergistic effects may occur and result in more rapid permeation than accounted for by the individual mixture chemicals.
Permeation rates may be used to calculate potential wearer exposure; however, several assumptions must be made about the extent of exposure and condition of clothing wear. Furthermore, there are few chemicals with dermal exposure limits, making it difficult to determine an acceptable skin exposure level.
