Acute toxicity

A waste has the characteristic of acute toxicity, when it is lethal at low doses in humans. It is considered that a residue has such a feature in the following cases:

a) When its toxicity by oral ingestion in rats, expressed as lethal dose 50 (LD 50 oral) shows in a laboratory test an amount equal or lower than 50 mg residue / kg of body weight.

b) When the value of their inhalation toxicity in rats, expressed as lethal concentration 50 (LC 50 inhalation) shows in a laboratory test an amount equal or lower than 2 mg of residue / l t.

c) When dermal toxicity in rabbits, expressed as lethal dose 50 (LD 50 dermal) shows in a laboratory test an amount equal or lower than 200 mg residue / kg of body weight.

The acute toxicity of a waste may be estimated based on the technical information available regarding the acute toxicity of their component substances. It is considered as a residue that has the characteristic of acute toxicity, when the percentage content in the residue of a toxic substance listed in Article 88 of the Health Regulations on Hazardous Waste Management or other acute toxic substance recognized as such by the supreme decree of the Health Ministry, exceeds the smaller of the acute toxic concentrations limits CTAL defined for that constituent, calculated as follows:

Oral CTAL = [oral LD ??50/50 mg / kg] x 100

CTAL inhalation = [inhalation LC 50/2 mg / L] x 100

CTAL dermal = [dermal LD ??50/200 mg / kg] x 100

If the waste contains more than one acute toxic substance is considered hazardous if the sum of the percentage concentrations of such substances, divided by their respective concentrations Acute Toxic Limits, is greater than or equal to 1 for any of the routes of exposure before mentioned.

C (1) / CTAL (1) + C (2) / CTAL (2) + ...... + C (n) / CTAL (n)> 1

Air pollutant

Any substance in the air that in certain concentrations can cause damage to humans, animals, plants or materials. Compounds can include almost any natural or artificial floating matter capable of being transported by air. These pollutants are in the form of solid particles, droplets, liquid, gas or combined. It is generally classified into two groups: 1) issued directly by identifiable sources and 2) those produced in the air by the interaction of two or more primary pollutants, or by reaction with the normal compounds from the atmosphere, with or without photoactivation. Excluding fever, fog and dust that are of natural origin, about one hundred contaminants have been identified and placed into the following categories: solids, sulfur compounds, volatile organic chemicals, nitrogen compounds, oxygen compounds, halogen compounds, radioactive compounds and odors.
