Toxins in Wheat crop study of harmful substances in wheat .pptx

Here’s a short, simple summary of “Toxins in Wheat”:

1. Toxicology: study of harmful substances in wheat.
2. Sources: pollution, fungi, pesticides, storage, farming.
3. Main toxins: mycotoxins (DON, ZEA, aflatoxins), pesticides, heavy metals (Pb, Cd, As).
4. Health impacts: nausea, vomiting, hormonal issues, cancer, liver and kidney damage.
5. Prevention: good crop management, monitoring, soil and water testing.
6. Detection methods: ELISA, AAS, HPLC.
7. Regulations: limits on DON, aflatoxins, and metals in wheat products.
Conclusion: controlling toxins ensures safe food and protects health.

3. Toxicology in wheat plants encompasses various harmful substances that can affect both the plants themselves and the broader ecosystem. Refers to the study of harmful substances or toxins in wheat, their sources, and potential effects on human health, animals, and the environment. Overview of Toxicology in Wheat crop

5. Mycotoxins Deoxynivalenol (DON) (also known as vomitoxin ), Zearalenone ( ZEA), Aflatoxins . Pesticide residues Insecticides, Fungicides, Herbicides Heavy metals Lead ( Pb ), Cadmium (Cd ) , Arsenic (As) Types of Toxins in Wheat Crop

6. Poses significant health risks to both humans and animals. Causing acute temporary nausea, vomiting, diarrhea, abdominal pain, headache, dizziness, and fever. Zearalenone (F-2) Vomitoxin (DON) Leads to disorders of the hormonal balance of the body. Causes diseases of reproductive system.

7. Cd uptake It accumulates in edible plant parts. This accumulation increases with the decrease of soil pH. Affects kidneys and cardiovascular system. Affects Digestive system (pancreas, liver, and adrenal gland ).

8. As. effect The major source of human exposure to As is crops and vegetables . Introduction of As in the food chain takes place by its excessive uptake from soil Having chronic and epidemic effects on human and animal health Can cause lung and skin cancers

11. Mycotoxins Monitoring Soil and Water Testing Prevention and Mitigation

12. Regulatory Aspects 500-1750 µg/kg for DON Lowering the limit to 200 μg /kg A flatoxins and heavy metals in food crops. 1 ppm of DON for finished wheat products intended for human consumption 70% of the UK wheat is found to be contaminated with DON, 95% of this meets safety limits

13. Detection and Analysis ELISA

14. AAS HPLC Detection and Analysis

15. Toxicology in wheat plants is a critical area of study to ensure the safety of wheat as a food source. The presence of mycotoxins, pesticide residues, and heavy metals can pose serious health risks to human and animals. Conclusion
