As a type of artificial growth hormone, the rBST is actually a kind of peptide hormone that is normally produced the the pituary gland of a cow. rBST can be created through the use of recombinant DNA technology.
One of the main reason why rBST is commonly injected on cows or cattle is to increase these animals’ milk production (Chaiyabutr et al., 2007). According to Schoenberg (2012), “the bovine form of ST is not recognized by receptors in the human body”. However, rBST can trigger a signficant increase in the cows’ IGF-I levels (Dohoo et al., 2003). Based on the study that was conducted by Dohoo et al. (2003), animals that are injected with rBST increases the risks of fertility-related problems (40%), increased risks for mastitis (25%), and showing signs of lameness caused by leg and foot problems (55%) among others.
The empirical formula of chlorpyrifos is C9H11Cl3NO3PS (Venugopal et al., 2012). Basically, the chlorphyrifos is a crystalline organophosphorus pesticide that is commonly used in killing insects and arthropod pests (Venugopal et al., 2012. Rauh et al., 2011). This chemical can kill insects and arthropod pests by inhibiting acetylcholinesterase (AChE) (Amitai, Moorad, & Adani, 1998).
Even though chlorpyrifos is considered as moderately toxic, exposing a pregnant woman to this particular chemical can lead to developmental and autoimmune disorders and the development of neurological deffects on the part of the fetus (Rauh et al., 2011). Exposing young children to this particular chemical can trigger delay in their motor and mental development and increase their risk of developing disorders like ADHD (Rauh et al., 2006), low birth weight (preterm), and below the normal head circumference at birth (Harley et al., 2011. Whyatt et al., 2004).
In the case of the adults, farmers who are often exposed to this chemical can increase their risk of developing lung cancer (Lee et al.,
