Table 1.

Concentration of inorganic ions, pH, osmolarity and total ammonia in raw sewage water collected from septic tanks containing developing A. aegypti larvae, pupae, and breeding adults.

Osmolarity (mOsm/L)	Total [NH3/NH4+] (mmol/L)	NH4+ (mmol/L)	pH	Na+ (mmol/L)	K+ (mmol/L)	Cl− (mmol/L)
29 ± 4.143	7.78 ± 1.217	4.57 ± 0.548	8.48 ± 0.134	4.25 ± 0.438	1.19 ± 0.108	8.24 ± 0.893

Values are shown as mean ± S.E.M. (n = 3 samples of raw sewage). Note: samples of freshwater were not analyzed here, however, freshwater [NH₄⁺] and osmolarity measurements can be found in text (see Results).
