The most hazardous heavy metals, including arsenic, cadmium, chromium, copper, nickel, lead, and mercury, have a profound impact on both the environment and human health, as outlined by the UN Environment Programme. Exposure to mercury, for instance, can harm various organs such as the brain, heart, kidneys, lungs, and immune system of individuals of all ages. Additionally, the nervous system of children can be affected, leading to diminished cognitive and learning abilities.
Even at low levels of exposure, lead can hinder the neural development of children. It can also have adverse effects on the heart, blood vessels, kidneys, and digestive system. Meanwhile, cadmium exposure can lead to lung irritation, kidney disorders, bones weakness, and may even increase the risk of lung, prostate, and kidney cancers.
The US National Oceanic and Atmospheric Administration highlights that heavy metals such as cadmium and lead are the most likely pollutants to cause harmful biological effects in the Abu Qir Bay, as reported in an Egyptian study published in the scientific journal 'Environmental Earth Sciences'.
Rather than receiving toys for Ahmed to share with others, a small respiratory device was donated to his family. Initially requiring daily sessions, Ahmed's condition improved over time, resulting in fewer sessions needed. With the option of visiting a nearby health center, his mother donated it to a critically ill newborn, stating, 'There are others who are in greater need.' This act has now become a cherished legacy passed among the children in these villages.
Amin's sister mentioned that her daughter, Nagham, has a cardiac lesion due to excessive pollution exposure. Their homes are situated close to pollution sources. She continued, her daughter is prohibited from any exposure to pollution, but there's little they can do.
The villagers, especially in the Tabia area, made numerous attempts to lodge complaints. Among them was Ashraf Abdel-Salam, who collected grievances from locals after losing his foot due to various illnesses caused by industrial pollution, yet these efforts proved futile. In 2019, Member of Parliament Mai Mahmoud promised to lead a team to the Tabia area to investigate residents' complaints about pollution in the sea. The investigation confirmed sea contamination and its color turning black due to waste accumulation. However, no changes were evident when we visited the area this year.
In the case of mercury concentration rates exceeding 0.71 micrograms per gram, its impact on the environment is extremely severe. Meanwhile, if cadmium records 1.2, its impact is low, and at 9.6, it's considered moderate, according to the minimum estimates by the US National Oceanic and Atmospheric Administration on heavy metals.
Mercury levels in most of the Bay increased by 21.83 at the Rashid outlet and 0.85 at the Maadiya area. Cadmium recorded a rate of 2.10 before the Maadiya area and 1.89 in the petroleum activity area.
