Abstract: Coffee is the most popular beverage in the world and the most consumed caffeinated beverage after water and tea. It contains a combination of several chemical components that, with the health benefits, most consumers start the day with at least one cup of coffee after eating and end the working day with coffee. It is considered an important part of modern-day life because it has an alarming effect on the human brain. In contrast, different groups report. They face unequal health risks and are therefore reluctant to drink coffee, suggesting individual differences in coffee intolerance. The purpose of this study was to briefly summarize the health benefits and risks of coffee consumption. Most informative reports suggest that long-term consumption of coffee and decaffeinated coffee can reduce the risk of many diseases. Among them, it is used to improve our physical performance, burn fat, reduce the risk of stroke, liver, prostate and colorectal cancer by 20%, the risk of Parkinson's disease by 25%. the risk of dementia and protect our mind, brighten our mood, help fight depression and minimize the risk of suicide by 50%. In addition, coffee drinkers have a lower risk of heart disease, with highly integrated DNA. It has also been reported that coffee consumption naturally lengthens sleep latency, decreases total sleep duration and efficiency, and worsens putative sleep functions. However, from the positive health perspective of coffee consumption, a recent study reveals that coffee consumption does not always provide protective benefits, since excessive consumption is associated with a negative impact or risk to our health. Some negative effects of coffee consumption on our health: reduces appetite, affects pregnant women, people with cholesterol, causes insomnia and restlessness, breast tissue cysts in women, digestive disorders related to incontinence and risk of headache In addition, it reduces the likelihood of fertility in women and men, causes allergies and abortions, violent heart contractions, anxiety, depression and the need for anti-anxiety drugs, inhibits the production of collagen in human skin, improves the hearing loss. it does not help with prolonged sleep deprivation, it interferes with ossification and may even lead to an increased risk of bone fracture. Finally, more recent studies have reported that the consumption of coffee is beneficial for our health when it is optimal, about four glasses on average. Further research will be crucial to clarify the health benefits and risks of coffee consumption.

Abstract: The aim of the work was the simultaneous determination of hydrocarbon biochemical oxygen demand - cBOD and nBOD (nitrogen) in the same water sample without using a nitrification inhibitor by the manometric method. Daily measurements of cBOD are determined by recording the pressure drop resulting from the absorption of carbon dioxide released by the oxidation of hydrocarbon organic matter by microorganisms with KOH (potassium hydroxide). Here, the processes of oxidation of mineral substances in water and especially the developing nitrification processes, which absorb oxygen dissolved in water and cause an additional pressure drop in the vessel, are a disturbing factor, for the measurement of which, in the daily 24-hour cycle of registrations, it is recommended to close the absorption hole of the vial with KOH for 8 hours. The 24-hour nBOD and cBOD results are calculated from the result of the pressure drop in these 8 hours. In the paper, in the form of a table, the detailed form of calculation of the recorded results of BODs at two pH-s of a natural water sample within 1-20 days is given. The possibility of anthropogenic impact assessment using this method is shown on the example of natural water. It is concluded that with the proposed method of measuring BODs records the complete and separate results of cBOD are recorded under conditions of developing nitrification in water. All information from both nitrification and BOD-full is recorded simultaneously, which gives a complete picture of the overall oxygen balance in the water. The proposed method is practically applicable and fully comparable with the results obtained by the standard manometric method.
