Toxicology

Environmental FateAquatic: Once the compounds enter the aquatic environment, whether sorbed or dissolved at low concn, the zinc dialkyl dithiophosphates will probably dissociate./Zinc O,O-Diisoalkyl Dithiophosphates/
Adverse Effects · 1 item

Reproductive Toxin - A chemical that is toxic to the reproductive system, including defects in the progeny and injury to male or female reproductive function. Reproductive toxicity includes developmental effects. See Guidelines for Reproductive Toxicity Risk Assessment.

Soil Adsorption/MobilityThese cmpds are expected to partition to the organic phase. They will probably sorb to humic matter and clay in the environ. The zinc is subject to exchange with other metals in natural water./Zinc O,O-Diisoalkyl Dithiophosphates/
Artificial Pollution Sources · 1 item

Zinc O,O-diisoalkyl dithiophosphates enter the environment through improper disposal of motor oils, greases and hydraulic fluids. They could also enter the environment from engine leaks, hydraulic pumps, gear boxes and torque converters if present in the fluids associated with these uses. /Zinc O,O-Diisoalkyl Dithiophosphates/

Environmental BiodegradationZDDPs should be readily metabolized by microorganisms. Degradation will probably be rapid unless toxic concn are present. Microorganisms should be able to attack the phosphate ester bonds./Zinc O,O-Diisoalkyl Dithiophosphates/
Environmental BioconcentrationCmpds may bioconcentrate unless metabolism is rapid. /Zinc O,O-Diisoalkyl Dithiophosphates/
Non-Human Toxicity Excerpts · 5 items

Application of a blend of primary zinc dialkyl dithiophosphate lubricant additives suspended in process oils did not incr the mutation frequencies of Salmonella typhimurium TA1535, TA1537, TA1538, or TA100, or significantly incr the transformation frequency of BHK cells. /Zinc Dialkyl Dithiophosphates/

Mixed esters of zinc dialkyl dithiophosphate (including diisocytl and diisodecyl esters) at 2 ml/kg/day were found to cause aspermatogenesis and tubular hypoplasia following 28 days of non-occluded, non-abraded dermal exposure to sexually immature rabbits. /Zinc O,O-Dialkyl Dithiophosphates/

Application of ZDDP (unspecified ester) into rabbit eyes produced severe membrane irritation with corneal injury persisting beyond 14 days. /Zinc O,O-Diisoalkyl Dithiophosphates/

ZDPP mixtures are primary skin irritants. Application to the skin of rabbits produced severe erythema and edema. /Zinc O,O-Diisoalkyl Dithiophosphates/

For more Non-Human Toxicity Excerpts (Complete) data for ZINC O,O-BISISODECYL DITHIOPHOSPHATE (8 total), please visit the HSDB record page.

Environmental Abiotic DegradationZDDPs do not exist in used motor oils since they are broken down by engine action. ZDDPs were not detected in motor oils used for more than 3,000 miles./Zinc O,O-Diisoalkyl Dithiophosphates/
Probable Routes of Human Exposure · 2 items

Dermal exposure is likely to individuals handling lubricating oils and hydraulic fluids. /Zinc O,O-Diisoalkyl Dithiophosphates/

Consumers performing automobile oil changes may be exposed through use of lubricating oil. Automobile and other machinery mechanics will also be exposed./Zinc O,O-Diisoalkyl Dithiophosphates/

Antidote and Emergency TreatmentWash skin or eyes with copious amt of water-see a physician.
Non-Human Toxicity ValuesLD50 Rat oral 2.31 mg/kg
