Write a few sentences (about 100 words) integrating a quote from any of the articles that you will be using in your paper. Be sure to connect your quote to the rest of your sentences. You can do this via signal phrases (“Smith argues” OR “According to Smith,” etc) or by integrating your quote as it grammatically fits into your sentence. Document your quote by using the APA in-text citation guidelines you have studied in this lesson.
When you are done posting your response, reply to at least one classmate in no fewer than 75 words. Comment on how effectively they have integrated a quote.
Your discussion post will be graded according to the following criteria:
80% – Thoughtful original post that properly integrates a quote from one of your sources in at least 100 words
20% – Thoughtful response to a classmate’s post that comments on how well they have integrated their quote with the rest of their sentences (at least 75 words)

Heavy metals, which have widespread environmental distribution and originate from natural and anthropogenic sources, are common environmental pollutants. In recent decades, their contamination has increased dramatically because of continuous discharge in sewage and untreated industrial effluents. Because they are non-degradable, they persist in the environment; accordingly, they have received a great deal of attention owing to their potential health and environmental risks. Although the toxic effects of metals depend on the forms and routes of exposure, interruptions of intracellular homeostasis include damage to lipids, proteins, enzymes and DNA via the production of free radicals. Following exposure to heavy metals, their metabolism and subsequent excretion from the body depends on the presence of antioxidants (glutathione, α-tocopherol, ascorbate, etc.) associated with the quenching of free radicals by suspending the activity of enzymes (catalase, peroxidase, and superoxide dismutase). Therefore, this review was written to provide a deep understanding of the mechanisms involved in eliciting their toxicity in order to highlight the necessity for development of strategies to decrease exposure to these metals, as well as to identify substances that contribute significantly to overcome their hazardous effects within the body of living organisms.
