Heavy Metal Content and Potential Health Risk of Geophagic White Clay from the Kumasi Metropolis in Ghana

This study sought to determine the levels of heavy metals in the studied geophagic clay samples and to determine the potential risks of heavy metals as cumulative carcinogenic and non-carcinogenic risks to the health of the consumers via oral (ingestion) and dermal exposure routes. A total of thirty (30) white clay samples were analysed using Niton Thermo scientific XRF Analyser (Mobile Test S, NDTr-XL3t-86956, com 24). The clay samples were found to contain essential elements such as Ca, Fe, K and Zn as well as toxic metals such as As and Pb. There were isolated cases of the presence of Hg and all samples had Cd levels below detection. Health risk indices such as hazard quotient and cancer risk were calculated and the results indicated that consumers are likely to suffer from cancer through ingestion of geophagic clay. Bioaccessibility studies were done on zinc and it did not indicate any potential toxicity due to zincs essential nature. The levels of heavy metals in some of the geophagic clay consumed by some residents in the Kumasi were high compared to the Permitted Maximum Tolerable Daily Intake (PMTDI) by (WHO/FAO) and may pose potential health threat over time.

Discussion Cannabis sativa makes small fruits which are usually named “seeds” although they are not technically a seed. Hemp oil is derived from the hemp seeds by cold-pressing or other means of macerating or squashing the seeds. Cold pressed oil is high in polyunsaturated fatty acids including various omega-3 and linolenic acids and antioxidants. It is used by some people for its nutritional value and “[a]ccording to an old legend, Buddha (Prince Siddharta Gautama) founder of Buddism, was able to survive eating only one hemp seed each day for six years.” The seeds themselves do not contain any psyc...

The growing field of onco-fertility has brought necessary attention to improving patients ’ ability to achieve a pregnancy after cancer treatment. However, relatively little is known about frequency of healthy births, particularly with regard to preterm birth, pre-eclampsia, and low birthweight, among survivors of cancers diagnosed during the young adult years.

CONCLUSIONS: Breastfeeding represents a protective mechanism only in patients without genetic breast cancer predisposing mutations. Environmental and reproductive factors can impact the risk and the age of onset of breast cancer in patients carrying pathogenic mutations, but the mechanisms of action are not fully understood.

Sandhya Shrivastava, Rupali Naik, Hema Suryawanshi, Neha GuptaJournal of Oral and Maxillofacial Pathology 2019 23(2):311-311 Microchimerism is the presence of cells from one individual in another genetically distinct individual. Pregnancy is the main cause of natural microchimerism through transplacental bi-directional cell trafficking between mother and fetus. In addition to a variety of cell-free substances, it is now well-recognized that some cells are also exchanged in pregnancy. Furthermore, it is now known that microchimerism persists decades later both in mother and in her progeny. The consequences of pregnancy-rel...
