Pesticide problems continued at Charles H. Hulse Public School on Monday when,
on the day the school reopened, three teachers and one student went home
complaining of headaches, nausea, itchy eyes and sore throats. The symptoms are
similar to those reported by numerous students and staff last month after the
school was sprayed with a pesticide intended for outdoor use. The school
reopened after more than a month of cleaning and renovations to rid it of the
pesticide smell. via
