Cotinine is detectable in blood for at least several days after exposure to tobacco smoke. Depending on how much you smoke, the level of cotinine in your blood will reflect a nonsmoker level in 7 to 10 days. The nicotine test that offers the longest detection window is a hair follicle nicotine test. These are rarely administered due to their expense, but they do exist.
High pH is NOT always BAD! But, high pH is NOT always GOOD, either! The recommendation that swimming pools should be operated at pH levels between 7.2 and 7.6 is almost universal.

Y-40: surface area of 21x18m, maximum depth is 40m with various intermediary depths and caves for technical activities. The swimming pool contains 4300mc of thermal water kept at a temperature of between 32-34Â°C so you can swim and dive in just your normal swimming costume rather than having to wear a wetsuit.
