Chemical Food Contaminant in detail

Pesticide Residue

• Meals grown organically have less residues than foods grown traditionally.
• According to organic certification programs, land must be devoid of chemical inputs for two or three years before organic cultivation may begin.
• Due to historical land uses and chemical drifts from conventionally managed farms, there may be low quantities of pesticides present.
• It must be below the permitted maximum residue levels.
• Biological control is the recommended approach to managing pests in organic farming.

Nitrates From Fertilizers

• Crops grown organically are said to have much less nitrates than those grown conventionally, especially nitrophilic leaf, root, and tuber crops.
  E.g.
  • Methaemoglobinaema (a disease that interferes with oxygen carrying capacity of blood).
  • Nitrosomine illness is caused by presence of secondary amines, which causes cancer in human beings.
  • Feroxyl nitrates, alkyl nitrates, vapours of HNO3 and nitrate aerosols causes respiratory illness.
  • Entrophication
  • Under certain conditions, nitrates may be converted to nitrosamines which are carcinogenic.
