Usage

Description

Lead arsenate, with the chemical formula Pb3(AsO4)4, is an odorless, white, heavy powder that is practically insoluble in water. It is not combustible and emits irritating or toxic fumes when exposed to fire. This toxic compound has been used as an insecticide and herbicide due to its ability to regulate growth in certain crops and control various insect pests.

Uses

Used in Insecticide Applications:
LEAD ARSENATE is used as an insecticide for controlling a wide range of insect pests, such as larvae of gypsy moth and boll weevil. It was also used for insect pests on apples and other fruit trees, garden crops, turf grasses, rubber, and coffee trees.
Used in Veterinarian Treatment:
In the veterinary industry, LEAD ARSENATE is used as a teniacide and insecticide to treat and prevent infestations in animals.
Used in Mosquito Abatement:
LEAD ARSENATE was employed for mosquito abatement in cattle dips, helping to reduce the spread of diseases carried by mosquitoes.
Used as a Growth Regulator:
In the agricultural industry, specifically for grape fruit crops, LEAD ARSENATE is used as a growth regulator to manage the growth and development of the plants.
Used in Soil Treatments:
LEAD ARSENATE is used in various soil treatments to control soil-inhabiting insects such as cockroaches, silverfish, crickets, and earthworms. This application is particularly relevant for maintaining golf greens, lawns, and airport turf adjoining runways to reduce bird hazards related to earthworms.

Health Hazard

Exposures to lead arsenate occur in work areas and it is absorbed into the body by inhalation of its dust and by ingestion. It is irritating to the eyes, the skin, and the respiratory tract, and causes adverse effects on the gastrointestinal tract, nervous system, kidneys, liver, and blood. Accidental ingestion of lead arsenate in the workplace causes cough, sore throat, abdominal pain, diarrhea, drowsiness, headache, nausea, vomiting, muscular cramp, constipation, excitation, and disorientation in the worker.
