What are two types of reproductive toxins

Reproductive toxins include physical agents (e.g. radiation), biological agents (e.g. viruses), maternal metabolic imbalances, and chemical agents. This section will focus on chemical reproductive toxins.

What is Category 2 reproductive toxicity?

Substances are classified in Category 2 for reproductive toxicity when there is some evidence from humans or experimental animals, possibly supplemented with other information, of an adverse effect on sexual function and fertility, or on development, and where the evidence is not sufficiently convincing to place the …

Is Veratramine a reproductive toxin?

Food and water were available ad libitum.

What type of hazard is reproductive toxicity?

Reproductive toxicity is a hazard associated with some chemical substances, which interfere in some way with normal reproduction; such substances are called reprotoxic. They may adversely affect sexual function and fertility in adult males and females, as well as causing developmental toxicity in the offspring.

Which of the following contaminants is toxic to both male and female reproductive systems?

Lead is toxic to both male and female reproductive systems. Lead can alter the structure of sperm cells and there is evidence of miscarriage and stillbirth in women exposed to lead or whose partners have been exposed.

What is a category 2 carcinogen?

Category 2 carcinogens are suspected human carcinogens. This is based on evidence obtained from human and/or animal studies but which is not sufficient for a Category 1 classification.

What is Reproductive Toxicity Category 1B?

CATEGORY 1B: PRESUMED: PRESUMED to produce an adverse effect on reproductive ability or capacity or on development in humans. The placing of the substance in this category is largely based on evidence from experimental animals.

What does it mean if a chemical is classified as a reproductive toxin?

Reproductive toxicity refers to adverse effects of a chemical substance/mixture on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring. Developmental toxicity pertains to adverse toxic effects to the developing embryo or fetus.

Which is an example of reproductive toxin?

Reproductive toxins include physical agents (e.g. radiation), biological agents (e.g. viruses), maternal metabolic imbalances, and chemical agents. … It is listed in Appendix V(j)-A as an “Example of Known or Suspected Human Reproductive Toxins”.

What are the two major hazard groups used to classify Whmis hazards?

WHMIS 2015 applies to two major groups of hazards: physical, and health. Each hazard group includes hazard classes that have specific hazardous properties.

Article first time published on

Is toluene a reproductive toxin?

Subacute exposure to a high level (2000 ppm) of toluene vapor elicited mild toxic changes in the kidneys, thymus, and reproductive organs of males. Toxic effects on fertility and reproduction were thus demonstrated not only in females but also in males exposed to toluene vapor in the present study.

What are systemic toxins?

A systemic toxin is one that affects the entire body or many organs rather than a specific site. For example, potassium cyanide is a systemic toxicant in that it affects virtually every cell and organ in the body by interfering with the cell’s ability to utilize oxygen.

What is sensitizer in chemistry?

A sensitizer is defined by OSHA as “a chemical that causes a substantial proportion of exposed people or animals to develop an allergic reaction in normal tissue after repeated exposure to the chemical.”

Who can be negatively affected by reproductive toxins?

Exposure to toxicants before and after conception can affect parents, fetuses, and newborns. Pregnant women tend to be concerned about three of the most common occupational health hazards (i.e., tobacco smoke, video-display terminals, and the quality of indoor air).

What chemicals affect the reproductive system?

The worst fertility disrupters are organochlorine compounds (chlorinated pesticides, polychlorinated biphenyls, and dioxins), bisphenol A (BPA), and organophosphate pesticides and herbicides. However, many other chemicals, metals, and air pollutants seriously damage fertility.

What effects do certain toxic chemicals have on the male and female reproductive systems?

Hazardous exposures can cause infertility in males by interfering with hormones, damaging the testes (thus affecting sperm production), or by damaging the sperm leading to a reduction in sperm count, viability, motility, or functional capabilities.

What is embryo fetal toxicity?

Embryotoxicity includes (1) production by a substance of toxic effects in progeny in the first period of pregnancy between conception and the fetal stage and (2) any toxic effect on the conceptus as a result of prenatal exposure during the embryonic stages of development.

What is a Category 1 aspiration hazard?

The most severe of the aspiration hazard categories (Category 1) is accompanied by the warning label “may be fatal if swallowed and enters airways,” while Category 2 aspiration hazards carry the warning label “may be harmful if swallowed and enters airways.” Both categories refer specifically to substances that cause …

What is meant by maternal toxicity?

By definition, maternal toxicity occurs whenever a chemical exposure during pregnancy produces adverse effects on the mother.

What are carcinogens Name any two carcinogens?

Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke.

What is the difference between carcinogen and mutagen?

Yep, mutagens change (mutate) the DNA, while carcinogens CAN mutate DNA they ALSO cause other factors that lead to cancer.

What are carcinogens Name any two carcinogens present in tobacco?

In summary, cigarette smoke contains diverse carcinogens. PAH, N-nitrosamines, aromatic amines, 1,3-butadiene, benzene, aldehydes, and ethylene oxide are probably the most important carcinogens because of their carcinogenic potency and levels in cigarette smoke.

What is reproductive damage?

Reproductive Harm occurs when a chemical interferes with the ability to produce normal, healthy offspring. This includes effects on the female and male reproductive systems, and effects on the developing embryo, fetus, or child, resulting from exposure during pregnancy.

What is reproductive toxicity test?

Reproductive toxicity tests assess a substance’s tendency to cause reproductive system effects, while developmental toxicity testing evaluates the extent to which exposure to a substance may harm a developing embryo or fetus.

What is target organ toxicity?

Target organ toxins are chemicals that can cause adverse effects or disease states manifested in specific organs of the body. Toxins do not affect all organs in the body to the same extent due to their different cell structures.

What are two types of information you can find on an SDS?

The SDS includes information such as the properties of each chemical; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the chemical.

What is immuno toxicity?

Immunotoxicity is defined as adverse effects on the functioning of both local and systemic immune systems that result from exposure to toxic substances including chemical warfare agents.

What are the 2 types of WHMIS training?

There are two types of WHMIS training. General Training, which is commonly referred to as “Education” or “Generic WHMIS Training”, and Workplace Specific Training.

Which 2 of the hazards below apply to gasoline?

Conditions to Avoid: Open flames, sparks, static discharge, heat and other ignition sources. Incompatible Materials: Increased risk of fire and explosion on contact with: oxidizing agents (e.g. peroxides). Not corrosive to metals. Hazardous Decomposition Products: None known.

What are the WHMIS categories?
