"But we have no idea about the clinical manifestations of poisoning with this substance, so we must trouble you."
The meeting room was so quiet that the ticking of the clock on the wall could be heard.
Zhaxi's mind buzzed. 1987, 1992, Zhou Huaixin, organophosphate insecticides; these fragments spun rapidly in his head, forming a picture he dared not imagine.
Yang Ping's voice broke the silence: "Are you saying that this compound might be the organophosphate insecticide that Professor Zhou helped develop thirty years ago?"
Director Zhang nodded: "It's possible, but we can't be certain yet. To determine the structure, we need more samples. And the samples can only be found in Professor Zhou's body tissues; there might still be residues in his liver, kidney, and adipose tissues. We need to do more precise extraction and purification, which will take at least two weeks."
Officer Yu asked: "If this compound is indeed the insecticide from thirty years ago, how toxic is it?"
