Ferrochrome or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight. [ 1 ] [ 2 ] Ferrochrome is produced by electric arc carbothermic reduction of chromite .
Chromite mining, chromium, and ferrochrome production can toxically effect the environment. [23] Chromite mining is necessary when it comes to the production of economic commodities. [24] As a result of leaching of soils and the explicit discharge from industrial activities, weathering of rocks that contain chromium will enter the water column.

According to Thomas Laqueur, [1] prior to the eighteenth century the predominant model for a social understanding of the body was the "one sex model/one flesh model".It followed that there was one model of the body which differed between the sexes and races, for example, the vagina was simply seen as a weaker version of the penis and even thought to emit sperm.
The sociology of the body and embodiment [145] takes a broad perspective on the idea of "the body" and includes "a wide range of embodied dynamics including human and non-human bodies, morphology, human reproduction, anatomy, body fluids, biotechnology, genetics".
Body culture studies describe and compare bodily practice in the larger context of culture and society, i.e. in the tradition of anthropology, history and sociology. As body culture studies analyse culture and society in terms of human bodily practices, they are sometimes viewed as a form of materialist phenomenology .
The social construction of the body is a hypothesis that affirms that the relationship between the body and the socio-cultural context occurs in both senses, and that society and culture influence the formation of its members to some extent. [1] The body has become a social construction, in whose delimitation have participated multiple disciplines.
