Phosphine (PH3) is a kind of chemical compound that is colorless but flammable and toxic. It does not smell pure phosphine but it is because some compounds have an extremely foul odor, such as garlic or rotten fish. In the meantime, commercially produced phosphine gas is added to garlic essence to detect leakage during use. Phosphine, also known as hydrogen phosphite, is a very toxic gas and is fatal to humans even at very low concentrations. In case of prolonged exposure, vision loss occurs in the eyes. One of the most important effects on the human body is irritation of the respiratory tract and chronic damage to the skeleton.
Phosphine gas is mostly used in pesticides. Phosphine is included in the formula of many pesticides used in the struggle against rodents and pests in cereals. In the textile industry, phosphine also acts as an intermediate in the synthesis of flame retardant chemicals for cotton fabrics. Phosphine is a highly toxic gas for all humans, animals, plants, in short, all life forms. People should not be exposed to this gas even at very low amounts. Poisoning is usually by inhalation. Does not penetrate the skin through the body. The toxicity limit value was determined as 40 ppm for a working week of 0,3. Phosphine is one of the most toxic pesticides. The toxic effect of insect control is reduced as the temperature decreases.
Our company performs phosphine (PH3) measurements within the scope of gas measurements. In these studies, the relevant legal regulations, standards and test methods published by domestic and foreign organizations are complied with. One of the standards used in these studies is:
- TS 3851 Phosphine residue determination in aluminum phosphorus treated cereals (spectrophotometric method)
This standard covers a spectrophotometric analysis method used to determine the amount of phosphine residue remaining in the stored cereals after spraying with aluminum phosphide.
