Beneath the tranquil surface of our planet lies a hidden menace, one that silently infiltrates ecosystems, poisons wildlife, and threatens human health. These insidious intruders are known as Persistent Organic Pollutants (POPs). They are a group of toxic chemicals that persist in the environment, bioaccumulate in living organisms, and pose significant risks to both the environment and human health. In this article, we delve into the perils posed by POPs, exploring their sources, impacts, and the urgent need for global action to mitigate their devastating effects.

Pollution of the world's waters has become one of the most pressing environmental challenges of our time. From plastic waste choking our oceans to industrial pollutants contaminating freshwater sources, the health of aquatic ecosystems and the communities that depend on them is increasingly under threat. However, amidst these challenges, there is hope. Through effective pollution management strategies, we can mitigate the impacts of pollution and work towards restoring the health of our waters. In this article, we will explore various approaches to pollution management and highlight the importance of collective action in safeguarding our precious water resources.

In the intricate tapestry of life, harmony in habitat is the symphony that ensures the balance and sustainability of our planet. Environmental sciences delve into the complex interplay between organisms and their surroundings, unraveling the delicate relationships that sustain life. From the microscopic interactions in soil ecosystems to the global dynamics of climate change, every aspect of our environment is interconnected. In this article, we embark on a journey through the dynamic world of environmental sciences, exploring the fundamental principles, emerging challenges and innovative solutions driving our quest for harmony in habitat.

The aim of this study was to determine the concentration of major and trace elements in tomato around selected areas of Tigray, Northern Ethiopia. The heavy metal analysis was done using Flame Atomic Absorption Spectroscopy (FAAS). The Mean concentration of metals (ppm) recorded for tomato found in the four sites: Shire Fe>Ca>Zn>Mn>K>Mg>Cu>Pb>Ni>Cd>Cr; Adwa Fe>Zn>Ca>Mn>Mg>K>Cu>Pb>Cr>Ni>Cd; Wukro Fe>Ca>Zn>K>Mn>Mg>Pb>Ni = Cu>Cr>Cd; and Alamata Fe>Ca>Zn>Mn>K>Mg>Cu>Ni>Cd>Cr>Pb. In all study areas; higher concentrations of Fe, Ca and Zn were recorded and concentration of Cd and Cr was found lower in the sites. The recorded metal concentration shows that except for Pb and Cd all values were found below the WHO permissible limits. The metal content of soil samples was also recorded in the four cites all values were under the permissible limits set for irrigation soil. The analyzed metal content in water samples was under WHO permissible limits used for irrigation purpose. Hence, Cd and Pb were above the maximum permissible limit by WHO. Pb and Cd concentrations might pose undesirable effect on the health of the community and they are toxic lesser naturally. So, this indicates the tomatoes grown in the areas need to get attention for the heavy metal risks.
