Before explaining the above topic let’s first know about what is pesticides. Pesticides are designed to kill insects, fungus, bacteria and other things that feed on crops and are vectors for disease, nuisances, and things that destroy property. Two types of pesticides are biological and chemical. Biological pesticides are often developed using fungi, bacteria and other organically present substances. Some biological pesticides are microorganisms that, with no manipulation, demonstrate natural effectiveness in targeted pest control. On the other hand, chemical pesticides are developed by using chemicals or toxic chemicals which kills crop insects or pest. Impacts of pesticides on our health Pesticides are poisons and, unfortunately, they will harm quite just the “pests” at which they’re targeted. These are toxic, and exposure to pesticides can cause a number of health effects which are linked to a range of great illnesses and diseases from respiratory problems to cancer. Should you be worried? Acute toxicity Pesticides are often acutely toxic. This suggests that they will cause harmful or lethal effects after one
Episode of ingestion, inhalation, or skin contact. The symptoms are evident shortly after exposure or can arise within 48 hours. They will present as respiratory tract irritation, sore throat and/or cough, allergic sensitisation, eye and skin irritation, nausea, vomiting, diarrhoea, headache, loss of consciousness, extreme weakness, seizures and/or death, Chronic (or long-term) toxicity, Pesticides can cause harmful effects over an extended period, usually following repeated or continuous exposure at low levels. Low doses don’t always cause immediate effects, but over time, they will cause very serious illnesses. Long-term pesticide exposure results in asthma; depression and anxiety; attention deficit and hyperactivity disorder (ADHD); and cancer, including leukaemia and non-Hodgkin’s lymphoma. Endocrine disruptors the term endocrine disruptor refers to substances that interfere with hormones and hormone balance. Hormones are the chemical messengers of the body. They are necessary to regulate different functions, in particular growth and reproductive functions. They can manifest as reduced semen quality with consequently decreased fertility, genital malformations, testicular and prostate cancer, early puberty, the appearance of cysts in the ovaries, uterus anomalies, breast cancer, pregnancy complications diabetes and obesity, neurological disorders, especially disorders in brain development etc., hyper and hypo thyroidism and thyroid tumours. Carcinogenic substances substance is considered carcinogenic when there is evidence that they can cause cancer. There are many different types of cancer, but all of them can be characterised by the development of abnormal cells that begin to divide without control and spread into surrounding tissues. Single exposure events rarely cause cancer but repeated contact (whether through ingestion or the eyes, skin or lungs) with the carcinogenic substance, even at very low doses, can lead to cancer. Combined effects: One of the foremost worrying issues associated with pesticide exposure is the incontrovertible fact that the consequences of individual chemicals are often enhanced or altered when combined with one or more other such substances. Early pesticides included the utilization of botanicals and straightforward elements or compounds, which wont to impact less damage to human health. Now knowing all the facts about the hazardous effects of chemical pesticides on humans, Hopefully, people will reduce the use of chemical pesticides and can start moving towards the usage of organic pesticides, which are safe for human health and the environment.
