Polycyclic Aromatic Hydrocarbons and Association with in Uterine Exposure and Asthma :: Medical, Health, Medicine

Scientists have studied the effectuate of polycyclic aromatic hydrocarbons in regards to many health defects in humans, one of them being bronchial asthma attack. Asthma is a chronic condition regarding the respiratory system. Muscles in the respiratory system, specifically the lungs and the trachea, boil down causing a narrowing of the passageways in which air flows through. The constrictions of the respiratory organs can cause many symptoms that include strained breathing and tightness of the chest (Friis, 2012). In the United States alone, asthma is considered to be the most communal long-term disease that affects particularly and most frequently children (Al-Daghri et al. 2013). According to Kyung Jung, asthma in children has multiplied since 1980, when it was a low 3.6 percent to a instanter high 9.6 percent (Jung et al. 2013). The fast agents, polycyclic aromatic hydrocarbons (PAHs) are precarious worldly created from the partial burning of petroleum-based chemicals th at have been known to be one of the collaborators for asthma (Friis 2012). Additionally, PAHs can be make by the incomplete burning of ingrained compounds, such as wood, coal, and especially tobacco (Al-Daghri et al. 2013). There have been studies conducted to ground the affects and higher prevalence of asthma in children who are capable to PAHs in an in utero state. Children exposed in the womb, along with asthma and the known causative agent, PAHs, will be the principle course of study. Four studies have been conducted to hit the books the serious effects of PAHs. The inquiry consists of work performed by Sophie Chu, Nasser Al-Daghri, Dr. Mathew Perzanowski, and Wan-yee Tang and each(prenominal) of their colleagues all of which directed their own studies and research in regards to pollution exposed to children and asthma. For instance, Nasser Al-Daghri directed research on children in Saudi Arabia and found that close to 3 million children experience the hardships of asthma (2013). For this reason and many others, PAHs and its effects in growing fetuses have been investigated worldwide. There is evidence from the findings of the previously mentioned researchers that in uterine exposure to PAHs are associated with childhood asthma. Sophie Chu and her colleagues postulated that exposures to PAH before birth and by and by birth would cause an intensification of airway hyperreactivity, thus showing signs of asthma. Chu collected mice for her research and acquired a mixture containing the same quantity of PAHs a pregnant cleaning woman would regularly consume. She also acquired a vaporized control solution made of almost entirely of decontaminated water (99.
