None Pb acetate was weakly positive inducing a 0.19–1.6%<br />

increase in trans<strong>for</strong>mation. There was a weak dose<br />

response. There were no statistical analyses <strong>of</strong> these data.<br />

Zelik<strong>of</strong>f et al. (1988)<br />

None Pb chloride did not induce morphological trans<strong>for</strong>mation. Patierno et al. (1988),<br />

Patierno and<br />

Landolph (1989)<br />

(both papers present<br />

the same data)<br />

None Pb chromate enhanced SA7-induced morphological<br />

trans<strong>for</strong>mation.<br />

Studied as a chromate compound. Role <strong>of</strong> Pb not<br />

mentioned or considered.<br />

None Pb chromate induced morphological and neoplastic<br />

trans<strong>for</strong>mation.<br />

Cells exhibiting morphological trans<strong>for</strong>mation grew in s<strong>of</strong>t<br />

agar and grew in nude mice.<br />

Studied as a chromate compound.<br />

None Pb chromate induced morphological and neoplastic<br />

trans<strong>for</strong>mation.<br />

Cells exhibiting morphological trans<strong>for</strong>mation grew in s<strong>of</strong>t<br />

agar and grew in nude mice.<br />

Studied as a chromate compound.<br />

None Pb chromate induced morphological trans<strong>for</strong>mation more<br />

potently (9-fold) than other chromate compounds.<br />
