hazard
The hazard associated with a chemical is its intrinsic ability to cause an adverse effect. It should be compared to risk, which is the chance that such effects will occur. Whilst a chemical may have hazardous properties, provided it is handled safely under contained conditions, any risk to human health or the environment is extremely low

hazard assessment
Hazard identification and establishment of dose-response relationship for observed adverse effects in the specified (eco)toxicological endpoints

Identification of the adverse effects which a substance has an inherent capacity to cause

Chlorine is one of the elements most frequently found in nature; it is even more abundant than carbon. Chlorides, i.e. salts containing chlorine, are one of the few raw materials which will not be exhausted within the foreseeable future, even if chlorine consumption were to increase. Naturally-occurring chlorine compounds are present in our blood, ...

oestradiol
Oestradiol is a female sex hormone of importance during the menstrual cycle and pregnancy. It plays a role in the development of typical female body characteristics such as the formation of breasts, soft skin, sexual organs and the pattern of fat distribution. It has high oestrogenic activity as a sex hormone

oestrogen
Oestrogens are hormones which are primarily produced in sexually mature female animals. They regulate the development of typical female characteristics (e.g. breast development) and the onset of the oestrus cycle. Small levels of oestrogens are also found in males

oestrone
In the body oestradiol is converted to oestrone. It is a female sex hormone, but its activity is less than that of oestradiol
