Prevention

Compliance with personal hygiene rules:

Shower;

Laundries for washing workwear;

Sanitary security guard;

Special wardrobe.

Mandatory passage of special instructions by individuals. At the

same time pay attention to knowledge:

Safety regulations and technological process;

The toxic properties of chemical substances;

First aid measures (antidotes, gastric lavage…)

Prevention

Medical examinations (preliminary and periodic);

Therapeutic and preventive nutrition.Use 5 special rations:

1 diet – for persons exposed to ionizing radiation;

2,3,4,5 rations - for individuals. Contact with industrial poisons.

These diets are designed to activate the biochemical processes in the body, during which a particular poison affects. Products contribute to: accelerated removal of poisons and reducing their absorption.

Prevention

Additional nutrition in the form of 0.5 liters of milk helps to increase the body's resistance, since it contains high-grade

proteins, salts, and vitamins.

Restriction of table salt and salty products.

An increased amount of vitamins, especially when exposed to poisons that

cause beriberi.

Prohibition of drinking milk when working with lead.

PESTICIDES substances of chemical or biological origin intended for the destruction of agricultural pests and used as growth regulators. Defoliants, desiccants.

Classification

By chemical composition: Organic – organochlorine,

organophosphate… Inorganic-preparations based on mercury,

sulfur, copper, and chlorine… As intended:

Insecticides-destruction of harmful insects, Acaricides-protection from ticks,

Zoocides – rodent control, Fungicides-protection against fungal

diseases, Herbicides-weed control,

Repellent – scare away the insects…

Pesticides

Properties of pesticides:

Toxicity.

Ability to accumulate data.

Persistence – stability in time.

Solubility in water – pesticides that are highly soluble in water easily enter aquatic ecosystems, and sometimes even into drinking water.

Lipid-water index – organisms containing large amounts of lipids are able to absorb and accumulate lipophilic pesticides from the soil.

Adsorption properties – polar compounds absorbed by organic matter

Pesticides

Properties of pesticides:

Adsorption properties – polar compounds absorbed by organic matter and clay are more stable in the environment than non- polar ones.

Volatility and vaporization.

Pesticides

To reduce negative consequences, new generations are being developed and the product range is being improved:

! More toxic and therefore more effective pesticide used in micro- doses, and is less harmful compared to the use of pesticide in large doses.
