ERRATA "On the mass-transfer of major salt constituents from sea water to atmospheric precipitation", by R. Sequeira (A tmospheric Environment 27A, 1123-1129, 1993).

The author regrets that the above paper appeared with some errors. Their corrections are given below:

On page 1124, Section 2, paragraph 9, lines 6-7, for " . . . ~1~2 is satisfied", read " . . . ~1~2 = 1 is satisfied".

On page 1126, Section 5, paragraph 2, line 6, for " . . . E ~ ~'>>~ = 1", read " . . . E ~ ~'>>~ ~ 1". In paragraph 3, line 5, for " . . . ~ = 0 . . . " , read " . . . a = 1 . . . " . In paragraph 5, line 4, for " . . . / ~ -va l ue . . . " , read " . . . f l ' -va lue . . . " .

"On the large-scale impact of arid dust on precipitation chemistry of the continental Northern Hemisphere", by R. Sequeira (Atmospheric Environment 27A, 1553-1565, 1993).

In the Abstract, the second sentence should read "Hence, a study of the distribution of the concentration of calcium in aerosol and precipitation is as important as sulphate, ammonium and n i t r a t e . . . " and not " . . . sulphate, and ammonium nitrate".

The qualifying terms, "introduction" or "see introduction" in the references should be omitted.

Reference "Zhao (1987)" should read "Zhao (1988)".

Page 1564, second paragraph, the formula "CaSO 4 . ~'2H20" should read "CaSO 4 . 2H20".
