W badaniu przeanalizowano właściwości ścieków odprowadzanych z garbarni w Etiopii. Próbki ścieków pobrano w miejscu odprowadzania w celu określenia parametrów fizykochemicznych. Stężenie chromu (3+) w ściekach określono za pomocą SLC 208. Analiza TSS, COD, Cl, amoniaku, siarczków i fosforanów w ściekach została również przeprowadzona w laboratorium przy użyciu metod APHA2540-D, APHA 5220 B-COD, APHA 4550-Cl-B, APHA 4500-NH3, SLC 202 i Hack Lange (LCK349). Średnie wartości poszczególnych parametrów ścieków porównano z wartościami normatywnymi określonymi przez Ministerstwo Środowiska, Lasów i Zmian Klimatu. Wyniki dla Cr(3+), pH, TSS, COD, Cl, amoniaku, siarczków i fosforanów wynoszą odpowiednio 27,6 mg/litr, 7,63 jednostki pH, 631,4 mg/litr, 1597,9 mg/litr, 2493 mg/litr, 111,2 mg/litr i 52,35 mg/litr i 0,78 mg/litr. Wyniki wszystkich parametrów z wyjątkiem pH i fosforanów były powyżej wartości normatywnych ustalonych przez Ministerstwo Środowiska, Lasów i Zmian Klimatu. Wyniki badania wykazały, że parametry fizykochemiczne ścieków odprowadzanych z garbarni zawierają wysokie stężenie zanieczyszczeń i mają wpływ na zdrowie ludzi oraz ekosystem wodny.

    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...
