Dear Editor,
It is important to promote public awareness as it relates to the use of mercury and its effects on human beings and the environment. Mercury emissions can result directly from natural activities, such as volcanic eruptions and the erosion of rocks. Humans also use mercury for mining activities, coal fired power plants and for manufacturing and processing needs such as thermometers.
The consumption of mercury-laden fish is also an indirect exposure to the substance which has been linked to cancer, birth defects and developmental anomalies. The government recently signed the Minamata Convention on Mercury – an international pact that aims to control mercury emissions. This was done during an international conference that was organised by the United Nations Environment Programme (UNEP) held just recently in Minamata, Japan.
Due to the environmental and health risks of mercury, the government of Guyana was prompted to support the implementation of this legally-binding global instrument on mercury. Guyana’s main aim is to assist in the control of mercury usage.
Mercury is a neurotoxin, which basically means that it has detrimental effects on the nervous system. It can damage the brain and lead to permanent physical and emotional disorders. Symptoms of mercury poisoning include social withdrawal, self-injurious behaviour, lack of eye contact, blank facial expression, repetitive behaviour and hypersensitivity to noises and touching.
Medical science has proven over the years that mercury toxicity, when caused directly or indirectly, can be quite devastating. Guyana should immediately readdress matters as it relates to mining techniques currently used. Strong educational campaigns and anti-mercury measures should be implemented to create awareness and minimise the effects of mercury.
Sincerely,
Kenrick Jodhan
