Water pollution from sewage has become a subject of considerable public and scientific concern, given its demon-strated extreme toxicity to human health and biological ecosystems. Hospital wastewater poses a serious health risk to staff, the public, and the environment. This study was conducted to determine the physical, chemical and biological parameters of hospital wastewater from Mohammed VI University Hospital in Marrakech, which is discharged into the municipal sewage system, where it mixes with sewage from urban areas without prior treatment. This study was conducted between October 2022 and January 2023 with a sampling frequency of 15 days each. Hospital wastewater samples were collected at the main collector of all manholes in the hospital.Physicochemical characterization of the effluents from each department showed that they are heavily polluted with organic matter, with average values in the range of 750 mg/L COD, 512.14 mg/L BOD5 and 879.86 mg /L TSS. These values are higher than those recom-mended in the Moroccan discharge standards. Total phosphorus, sulfates, nitrates and nitrites are 5.92 mg/L, 427.97 mg/L, 7.39 mg/L and 0.60 mg/L, respectively. Bacteriological characterization shows that fecal coliform bacteria reach 12×106 CFU/100 mL. These effluents also contain pathogens responsible for nosocomial infections, especially Staphylococcus aureus. The ratio COD / BOD5 is about 1.46, a value indicating that hospital wastewater is readily biodegradable. Therefore, proper treatment of these hospital effluents is essential due to their physicochemical and pathogenic bacterial load, which can negatively affect public health and carry the risk of spreading epidemic diseases.

The analysis of the number of died men and women of different age per 100 000 persons of the corresponding sex from 1985 to 2002 in the city Kyiv was conducted. It is established that in the wide range of ages the phenomenon of the morbidity ratio of persons of different age is of a non-linear character. It is found the availability of the significant effect (19,6%; p<0,001) on the degree of this ratio. Four specific periods, associated with different possible mechanisms of the effect of the psychoemotional strain on the human body, have been specified in the dynamics of the sex ratio. It is established that the psychoemotional factor affects persons of different age groups specifically. In this, its effect on persons of able-to-work age, is the most threatening. A quantitative assessment of the population health of different age groups with due account of mortality ratio of persons of different sex has been proposed. The explanation of changes of sex ratio in populations, based on the theory of evolution in their development, is presented.

Przeprowadzono analizę liczby zgonów kobiet i mężczyzn w różnym wieku na 100 000 mieszkańców miasta Kijów obu płci, obejmującą lata 1985-2002. Założono, że w szerokim przedziale wiekowym zjawisko wskaźnika umieralności kobiet i mężczyzn w różnym wieku ma charakter nieliniowy. Stwierdzono istotny wpływ napięcia psychoemocjonalnego (19,6%, p<0,001) na wysokość ww. wskaźnika. Cztery poszczególne okresy, związane z różnymi możliwymi mechanizmami wpływu napięcia psychoemocjonalnego na organizm człowieka, zostały określone w dynamice wskaźnika płci. Ustalono, że czynnik psychoemocjonalny wpływa w różny sposób na osoby w różnych grupach wiekowych. W szczególności, jego wpływ na osoby w wieku produkcyjnym jest najbardziej groźny. Zaproponowano ocenę ilościową stanu zdrowia ludności w różnych grupach wiekowych z należytym uwzględnieniem wskaźnika śmiertelności osób obu płci. Przedstawiono także wyjaśnienie zmian współczynnika płci w populacji, w oparciu o teorię ewolucji w ich rozwoju.
